VRM Temperatures?

post #1 of 5
Thread Starter 
Hey all i recently built an x79 system consisting of a

Rampage IV Black Edtion
4930k
2x GTX 770

64gb ddr3 1600 (patriot viper black)


AX1200i


My question goes out to seasoned experienced builders. since it is very hard to find accurate readings of vrm temperatures via software, some people on other forums are saying to go by touch. i do not liquid cool my vrm's but they are saying if the heatsink is not burning hot but mildly warm to the touch it is a safe bet that everything is ok. the cpu idles and caps at VERY good temperatures and the psu is very cold as well. when i place my index finger gently on the heatsink of the vrm array above the cpu, it is not at all hot but just a bit warm... ive built many systems in my time but i guess ive never felt the need to check on vrm temperatures because i dont overclock majorly and all of my systems have been solid. the system in question also runs very solid with a 4.2ghz overclock but i guess im just a bit nervous since ive never built something of this nature before.

and i know peoples definitions of warm are different but i can assure you its no warmer than a LCD tv that has been on for a good 6 hours it dosnt feel unhealthy warm it just feels like its mildly warm... same goes to the ram modules slightly warm but not alarming. should i be concerned? ive run this system constantly for about a month now and have experienced no issues whatsoever. i just now noticed a bit of heat when i installed another 4 ram modules so for all i know it could have always been like this and is the nature of the beast... should i be worried or just get over myself ? confused.gif

Any advice or insight you guys have is welcomed and appreciated!

Load the system with a strenuous stress test, let it warm up for a few minutes, then put you finger on a surface as close to the PCB as possible in the immediate vicinity of the VRM FETs.

If it's anything less than immediately and acutely painful, it's probably fine.

I wouldn't worry then.

Only total garbage boards have any VRM components not rated for at least 105C, and the MOSFETs themselves are normally rated for 125-150C.

Cooler is better, but if you can't burn yourself at peak load, you are probably pretty safe.

What would cause a VRM temperature spike?

I'm running an AIDA stress test and keeping an eye on temps of certain things and I noticed that the VRM temp was 61 for a while and suddenly it shot up to 123 and it quickly dropped to 61c again.

What's that all about??

BTW I'm running a 5960X on 4.2Ghz and vcore of 1.184
